Wabash National’s SuperTruck trailer technology reduces weight, improves aerodynamics
Wabash National Corp., participating in the Department of Energy’s SuperTruck program, has developed a trailer that reduced drag coefficient by more than 30%. The SuperTruck program, a five-year research and development initiative, focused on improving freight efficiency (the amount of freight hauled per gallon of fuel used) by 50% compared to 2009 base model heavy-duty
Unpacking NACFE’s confidence report on trailer aerodynamics
The North America Council for Freight Efficiency (NACFE), which partnered with the Carbon War Room (CWR) to form Trucking Efficiency, recently released a Confidence Report to provide an unbiased review of tractor aerodynamic technologies available on the market today, and to increase investment in cost-saving tractor aerodynamic technologies. Tractor aerodynamics increase fuel efficiency by lowering air
How to save fuel with improved truck and trailer aerodynamics
When running a heavy-duty fleet, there’s no such thing as small savings. Even a seemingly small percentage of fuel economy saved can add up to thousands of dollars and be the difference between a profitable fleet and one that lags behind the competition. That’s why a large variety of aerodynamic products are available to help
Investing in aerodynamics to improve fuel efficiency
Wind resistance is a total drag—literally. Wind resistance is one of the top forces working against the truck as it runs down the road. (The other factors being: grade resistance; tire rolling resistance; and engine accessory and/or drivetrain losses, according to Cummins MPG Guide: “Secrets of better fuel economy”.) Did you know that every 2%
Putting heavy-duty truck aerodynamics to the test
In the fight for fuel efficiency, fleet managers are assaulted with a litany of efficiency products that claim to reduce fuel usage. The aerodynamic product category is starting to come into its own, where the impact has shifted the question from “Do these products work?” to “How do these products work for my fleet?” There
Kenworth offers optional upper bunk, roof fairing aerodynamics
An enhanced 52-in. mid-roof sleeper offering for the Kenworth T680, with the addition of an optional upper bunk, and an aerodynamic roof fairing is now available. The 28-inch wide foam upper bunk for regional haul applications that require a second sleeper berth is for use while the vehicle is parked. The T680 52-inch sleeper is
Vehicle aerodynamics and the future
While truck and engine manufacturers are working to boost fuel economy and reduce emissions in the face of looming regulations, it’s a timely opportunity to recap aerodynamic devices and the benefits they offer fleets.
Time running out for CARB compliance on trailer aerodynamics
Fleets and owner-operators who travel into California must have aerodynamic devices as of Jan. 1, 2013.
ATDynamics invests in rear-drag trailer aerodynamics
ATDynamics said it continues to expand its TrailerTail product line, most recently adding the TrailerTail Trident, an adaptation of the standard TrailerTail specifically designed for lower-mileage drop and hook operations.
Trailer aerodynamics: facts, not factoids
The acceptance of trailer fuel-saving drag reduction technology continues to be suppressed by disruptive claims and poor understanding of aerodynamics. Here are a few aerodynamic facts to bridge the knowledge gap.
